GEA : Specialised coolers for power industry

GEA Maschinenkühltechnik GmbH (www.gea-gmt.com) is one of the 250 companies within the GEA Group and belongs to its Heat Exchangers segment. The company is into the manufacture of thermo-technical components for power engineering and drive technology for more than 80 years.

GEA Maschinenkühltechnik serves the power industry with its world class coolers that include:
• Charge Air Coolers for diesel and gas engines
• Closed Circuit Coolers for generators and electric motors
• Recirculation Coolers for large electrical motors and medium size generators

Charge Air Coolers

These coolers manufactured for use in the marine and onshore/offshore fields are custom made for individual engine designs, particular installation criteria and varied operational conditions.

They can be used in special gas/biogas engines with use of special material and modern coating technology.

The recent development of stainless steel finned tube system has helped in increasing the corrosion resistance significantly.

Closed Circuit Coolers

GEA Maschinenkühltechnik is one of the leading manufacturers in air cooling for generators, electric motors and other electric machines.

Requirements for generators up to 10,000 KW power dissipation can be realised.

GEA’s hydrogen coolers are designed to increase the capacity of generator cooling systems, to offer optimal heat exchange and minimal material usage.

Recirculation Coolers

The recirculation coolers are generally used for the cooling of electrical machines as well as medium-sized generators such as wind power plants.

Use of special air circulation system transmits air in a hermetically sealed circulation and avoids pollution of the machine and also cost intensive cooling.

These coolers are equipped with one or more closed circuit coolers and are installed and sealed directly on the generator. The warm air of the generator passes through the recirculation housing is cooled by the closed circuit cooler and afterwards is led to the generator to carry away waste heat.
